The present invention provides a method for producing a multilayer structure, comprising the steps of: providing a composition comprising a Fe-Cr alloy powder and at least one of the oxides of Fe, Cr, Ni, Co, Zn, Cu; forming a first layer of said composition; forming at least one additional layer on one side of said first layer; heat treating said layers in an oxygen-containing atmosphere; and sintering in a reducing atmosphere so as to provide a final alloy, wherein the amount of Fe in the final alloy of the first layer after the sintering step is in the range of from about 50-90% by weight, based on the total weight of the final alloy.
La présente invention se rapporte à un procédé de production d'une structure multicouche qui comprend les étapes suivantes: utilisation d'une composition comportant une poudre d'alliage Fe-Cr et au moins un des oxydes de Fe, Cr, Ni, Co, Zn, Cu; formation d'une première couche de cette composition; formation d'au moins une couche supplémentaire sur un côté de ladite couche; traitement à chaud desdites couches dans une atmosphère contenant de l'oxygène; et frittage dans une atmosphère réductrice aux fins de l'obtention d'un alliage final, la quantité de Fe dans l'alliage final de la première couche après l'étape de frittage se situant dans l'intervalle compris entre 50 et 90 % environ en poids, sur la base du poids total de l'alliage final.
